Characterizing self-heating dynamics using cyclostationary measurements
Self-heating in surround gate (e.g., nanosheet, nanowire, and FinFET) transistors degrades their on-current performance and reduces their lifetime. If a transistor heats/cools with time constants much...
A coplanar electrode operating mode for piezoelectric energy harvesting and self-powered sensing
Piezoelectric semiconductors have emerged as a prominent area of research in recent years due to their unique combination of piezoelectric and semiconductor properties. In this Letter, we propose a pi...
Unconventional in-plane field-like spin–orbit torques induced by rare-earth Dy interface in Py/Dy/Pt tri-layers
Spin transport across an interface in energy-efficient spintronic devices, especially for spin–orbit torque applications, has sparked interest in the spintronics community. Here, we employ a rare-eart...
